Major League Baseball is considering one of two matchups for its 2020 series in London: Cubs versus Cardinals or Mets versus Nationals.

Two people familiar with the discussions told the Associated Press of the potential matchups. They spoke on condition of anonymity Friday because no announcements had been authorized. An announcement is expected after opening day.

MLB’s first games in Britain are scheduled for this summer, when the World Series champion Red Sox play the Yankees at London’s Olympic Stadium on June 29-30. The venue was built for the 2012 Olympics and reconfigured for the Premier League club West Ham United.

Baseball’s collective bargaining agreement calls for a 2020 opener in Asia, April games in Mexico, May games in Puerto Rico or the Dominican Republic and June games in Britain.

No universal DH — for now: Don’t look for a National League designated hitter this season or for new antitanking rules in the June amateur draft.

MLB Commissioner Rob Manfred said Friday that management is focused on pace-of-game changes for 2019, and bolder ideas proposed by the players association are too complex to be put in place for this season.

Speaking Friday after an owners meeting in Orlando, Fla., Manfred felt encouraged the union responded to management’s proposal for a pitch clock and a three-batter minimum for a relief pitcher unless an inning ends.

“Some of these items need to be part of broader discussions that certainly will continue after opening day, and I hope we can focus on some of the issues that need to get resolved quickly in the interim,” Manfred said.

Baseball is in its third year of a five-year labor deal, one in which the free-agent market has slowed considerably — even with premier players available such as Bryce Harper and Manny Machado. Management would discuss larger changes as part of a deal for a new collective bargaining agreement extending beyond December 2021.

Management presented its latest proposal Jan. 14, one that included a requirement that pitchers face at least three batters or finish an inning.

Players responded Feb. 1 with a broader plan, renewing their push for the DH in all games, an earlier trade deadline aimed at discouraging teams with losing records from trading stars, increasing service time for top young stars called up early in the season and rewarding and penalizing teams in the draft based on their records.

Lindor injured:The Indians might start the season without their best player. All-Star shortstop Francisco Lindor will miss spring training — and maybe the start of the season — with a strained right calf.

One of baseball’s top all-around players, Lindor recently was injured while working out in Orlando. Team physician Mark Shickendantz confirmed a moderate sprain.

The Indians anticipate Lindor, 25, missing up to nine weeks, which would place his return sometime in early April. They open the season against the Twins on March 28 in Minnesota.
